K2 Space

K2 Space (K2 Space Corporation) is a Los Angeles / Torrance, California aerospace startup that designs and manufactures high-power "Mega Class" satellite buses. Its platforms deliver roughly 20kW of array power and up to one metric ton of payload capacity - about ten times the power and payload of conventional buses - to maximize the throw-weight of next-generation launch vehicles like SpaceX Starship and Blue Origin New Glenn. K2 builds radiation-tolerant, vertically integrated (80% in-house) spacecraft with redundant avionics and high-delta-v propulsion for LEO, MEO, GEO and cislunar missions, serving commercial and U.S. government / defense customers. Backed by First Round Capital, Lightspeed Venture Partners and Redpoint Ventures, the company raised a $250M Series C at a $3B valuation and is preparing its first production satellite, GRAVITAS. K2 Space is a hardware company with no public developer API; this profile tracks its identity and web presence in the API Evangelist network.

K2 Space is profiled on the APIs.io network. Tagged areas include Company, Hardware, Aerospace, Satellites, and Space.
